5. USB DRIVERS INSTALLATION

5.1. Introduction

This paragraph provides hands-on instructions on how to properly install the Universal Serial

Bus (USB) drivers for the AMI interface module.

You can use the USB interface on standard PCs equipped by one of the latest Microsoft

Windows operating systems with plug-and-play capabilities and with support for the Universal

Serial Bus: Windows 2000, Windows XP, Windows Vista, Windows Server 2003, etc. These

drivers work only in the 32-bit version of the operating system.

Please note that you cannot install the AMI drivers in Windows 98/Me.

In addition, please remember that you must log on as full Administrator in order to install

the USB drivers.

5.2. Driver Signing Issues

Currently the USB drivers for the AMI are not digitally signed. In order to allow the installation

of the drivers, CTI recommends setting the Driver Signing Options either to Ignore or to Warn

both in Windows 2000, XP and Vista.

In order to open the Driver Signing Options dialog box, right click on My Computer, then select

Properties >> Hardware >> Driver Signing:

verified that only XP actually issues a warning to the user whenever he/she starts the installation of

the drivers. Under XP the following dialog box appears twice during the setup:
